We review the Al ages of chondrules in various type 3.0 chondrites. The Al ages of chondrules are 1–3 Myr after calcium-aluminum-rich inclusion (CAI) for LL3.0, CO3.0, and Acfer 094 (Ungrouped C 3.0). Available data for chondrules in CR chondrites indicate that many chondrules are relatively younger (‡3 Myr), although data from chondrules in CR3.0 are not yet available to confirm their younger ages. The total ranges for the Al ages of chondrules in a single chondrite group are more than 0.5–1… CONTINUE READING
